DESCRIPTION
These Instructions explain the proper procedures for installing and
testing TraceTek TT1100-OHP sensing cables. TT1100-OHP sensing
cables are primarily intended for use on overhead piping to detect a water
leak originating from a small pin hole or crack in the pipe. The wicking
action of the absorptive synthetic fiber outerbraid on the TT1100-OHP
cable can catch and hold a small drip or trickle of water– to ensure
sufficient wetted length to generate a leak alarm. TT1100-OHP can also
be used on floors, in drip pans, in sumps and trenches and similar flat
surface applications, however TT1000 standard water detection cable may
be better suited to flat surfaces.
Important Notes
When used to monitor suspended or rack mounted pipe, TT1100-OHP
sensing cables must be attached to the pipe at the lowest point where
any water leak is most likely to drip from the pipe system. This will be the
6 o’clock position on horizontal piping but other mounting locations and
techniques may be necessary if site conditions are unusual. In particular,
special consideration should be given to pipe supports, couplings, “T’s”,
valves and other fittings. It is the responsibility of the installer to position
the cable such that any leak will drip onto the cable.
The sensor cable cannot stop a leak. In some installations the materials
or structures beneath the pipe system may be so critical or valuable,
that a drip tray system should be considered in addition to the sensor
cable installation. TT1100-OHP is intended to alert the user that a pipe or
system is leaking but it cannot prevent collateral damage if the leak is not
contained and repaired immediately.

Clean and prepare the pipe or area where the cable will be
installed.
1. Verify that major construction is complete.
•Cleanthebottomandsidesofthepipewherethe
cable will be installed to remove any residual waste or
contamination.
•Ifthecablewillbeplacedindriptrays,makesureto
wipe the surface of the drip tray and remove any liquids
or debris.
•Forsumps,containmenttrenches,andsubfloor
applications, install TraceTek hold-down clips. For
TraceTek TT1100-OHP series sensing cables, use 1/2-
inch (13 mm) hold-down clips (TT-HDC-1/2-NA-50).
•Cleanthefloorsurfacewherehold-downclipswillbe
placed so adhesive can work properly.
•Positionhold-downclipssothesensingcablewill
provide the desired leak detection coverage. To best
secure the cable, alternate the direction of the hold-
down clips, and install them at intervals of no greater
than 6 feet (2 m) and at every change in direction (at
sides of trench, for example).
Important: Let the adhesive dry per manufacturer’s
recommendation before proceeding with sensing cable
installation.
Check each length of sensing cable before installation.

Connect, orient, install, and test each length of sensing cable in
sequence
1. Connect a Modular End Termination (TT-MET-PC) to the first sensing-cable
length to be installed.
2. Orient sensing cable so the connector used with the end termination will
be the furthest away from connection to the TraceTek alarm module. Work
out from the alarm module connection. For sensing cable on reels (lengths
over 10 feet (3 m)), put the reel on an axle and pull the cable out.
3. Install sensing cable in accordance with the leak detection layout plan.
A. For pipeline applications:
• Positionthecablealongthebottomofthepipeandusetiewrapsto
secure the cable at the 6 o’clock position. Maintain cable position
within 1/4 inch (6 mm) of 6 o'clock position.
• Tiewrapsshouldbelongenoughtogoaroundthepipeandthesen-
sor cable.
• Useonetiewrapevery12into18in(300to450mm)alongthepipe
with extra tie wraps at fittings or bends as needed.
Important: It is the installer’s responsibility to position the sensor cable
correctly. The cable must trace the lowest point of the pipe or fittings
such that any water leaking from the pipe or fittings will drip onto the
cable surface as it drips off the bottom of the pipe or fitting. Do not
install the cable on the top or side surface of a pipe. Do not spiral the
cable on horizontal pipe.
Exception: If the cable is used to trace vertical pipe, the cable should be
spiraled around the pipe and secured with tie-wraps.
B. For sumps, containment trenches, and subfloor applications:
• Pullthecablealongsidetheinstalledhold-downclips;minimumbend
radius is 2 in (50 mm). Leave 6 in (150 mm) of sensing cable on each end
for the connector service loop.
Important: Verify that the adhesive securing the hold-down clips has
dried; liquid adhesive must not contact the cable.
Push sensing cable into the hold-down clips and position the sensing
cable to lay flat on the surface to be monitored. Secure by snapping
hold-down clip end into base.
4. Test each length of sensing cable after installing it and before attaching
it to cable already installed. Confirm that the sensing cable is clean and
intact by following the Sensing Cable Test Procedure.
5. Connect the sensing cable to the cable string (lengths of sensing cable
connected in series) previously installed.
For sumps, containment trenches, and subfloor applications:
• Leaveaserviceloopateachconnectorasshown.
• Marktheconnectorpositiononthelayoutplan.
• InstallTraceTekmappingtag(TT-TAG).
• Note: As an extra precaution on large installations, periodically test the
entire cable string to confirm that all installed sensing cable is still clean
and intact.
• Unplugtheendterminationandconnectittothenextlengthofsensing
cable to be installed.
6. Repeat the installation sequence for each length of cable.

Complete the system
1. Install other TraceTek components (such as Modular
Branching Connectors, Weighted Lengths, and Modular
Jumper Cables) as called for in the system layout. Complete
the sensing circuit.
Note: All components of the system have male or female metal
connectors or both. The male connectors are oriented toward
the instrument panel. As new sections of cable are added to
the main leg or branch, each newly added section should end
with an open female connector. The end of each branch or
main leg is terminated with a male end termination.
2. Test the sensing circuit (or portions of it) to confirm that the
sensing cable is clean and intact. Follow the Sensing Cable
Test Procedure.
3. Connect the sensing circuit to the TraceTek alarm module
and activate the system as soon as is practical. Use the
alarm module to monitor the sensing cable during the final
stages of construction.
Take precautions if installation is incomplete at end of
work day.
At the end of the work day:
• Ensurethattherearenoopenconnectors.Eachsensing
cable should be connected to a Modular Leader Cable (TT-
MLC-PC), Modular End Termination (TT-MET-PC), and/or
other sensing cables; check both ends of the cable.
• Testandrecordtheconditionofinstalledsensingcablefol-
lowing the Sensing Cable Test Procedure.
• Ifpractical,connecttheinstalledsensingcabletothe
TraceTek alarm module. Test the system and put it in opera-
tion following the alarm module installation instructions.
At the beginning of the next work day:
• Checkthattheinstalledsensingcableiscleanandintact
following the Sensing Cable Test Procedure. Compare the
results with those obtained at the end of the previous work
day. If necessary, investigate and correct problems before
proceeding.

Sensing Cable Test Procedure
Method with TraceTek Portable Text Box (PTB)
1. Ensure the end termination is connected to the sensing cable.
If checking several lengths of sensing cable in series (a cable
string), ensure they are all connected.
2. Connect the PTB to the sensing cable(s) using its adapter, as
illustrated.
3. Verify that the sensing cable is intact; follow the operating
instructions printed inside the lid of the PTB itself. If a cable
or connection is broken, the PTB illuminates its LED indicating
“cable break,” and displays a “1” in the leftmost position of its
LCD display. If the cable string is intact, the PTB measures the
system length.
• Ifthecablestringisnotintact,applythistestprocedureto
segments of the system to identify the open connection or
damaged modular length.
• Note: If a heat-shrink tube must be removed to access a con-
nector, refer to Oversleeve Removal Instructions (H54258).
4. Check the condition of the sensing cable(s), again following the
PTB operating instructions. If the sensing cables are clean and
free of contamination, the current measured should be below
10 µA. If the reading exceeds 10 µA, use the PTB to locate the
liquid or contamination and take appropriate corrective action.
Method with Ohmmeter
1. Ensure the end termination is connected to the sensing cable.
If checking several lengths of sensing cable in series (a cable
string), ensure they are all connected.
2. Connect a Modular Leader Cable (TT-MLC-PC) to the sensing
cable.
3. Verify that the sensing cable is intact:
• Loop1:Measuretheresistancebetweentheyellowandblack
wires of the leader cable as illustrated.
• Loop2:Measuretheresistancebetweentheredandgreen
wires of the leader cable.
The readings should roughly equal a multiple of the length of
sensing cable:
3.9 times the length of sensing cable or 12.8 times the length
of sensing cable.
Example: 3.9 x 50 ft of cable = 195 Ω
12.8 x 15 m of cable = 192 Ω
In addition, the resistance of the two loops should be within 5
percent of each other.
If the cable string is not intact, apply this test procedure to
segments of the system to identify the open connection or
damaged modular length.
Note: If a heat-shrink tube must be removed to access a con-
nector, refer to Oversleeve Removal Instructions (H54258).
4. Check the condition of the sensing cable. Measure the resis-
tance between the black and green wires of the leader cable.
If the reading is below 20 megohms, apply this test procedure to
segments of the system to identify the modular sensing cable
length(s) affected, locate the liquid or contamination, and take
appropriate corrective action.

Complete System Connections and Layout
A. TT1100-OHP is available in a variety of pre-cut and terminated
lengths. Each cable has a female plastic connector on one
end and a male plastic connector on the opposite end. Cable
sections plug together like extension cords.
B. (Optional) A branch connector (TT-MBC-PC) is used to connect
and branch “T” lines. The branch connector has one male
connector and two female connectors. For mapping purposes,
the cable connected to the center leg of the branch connector
will be counted first, then the distance measurements will
continue from the second female connector and continue along
the rest of the system. A dead band of 15 ft (5 m) is inserted
at the beginning and end of each branch to avoid any location
ambiguity.
C. (Optional) It is permissible to have TT-MBCs installed on
branches as needed to fully trace a pipe system.
D. Install an end termination (TT-MET-PC) at the end of the main
line and each branch line. (Note: A good check on the system
design and bill of materials is that the total number of end
terminations installed in the system should equal the number
of branch connectors plus one)
E. (Optional) Install jumper cables (TT-MJC-xxx-PC) as needed to
connect sensing cable sections if they are spatially separated.
Jumper cable is available in various pre-cut and terminated
lengths and is also available in bulk form for long distance runs
between the sensor cable and the instrumentation point.
F.Install a leader cable (TT-MLC-PC) between the sensor cable
and the monitoring instrument. The factory standard length
of leader cable is 12 ft (4 m). It has a female plastic connector
on one end and four tinned leads on the opposite end for
connection at the instrument’s sensor cable terminal block. In
some installations the distance between the instrument and the
start of the sensor cable run will be much greater than 12 feet.
In those cases a simple solution is to purchase a jumper cable
of sufficient length, then cut off and discard the male connector
and any extra cable. Bulk jumper cable and connector kits are
also available for lengths that exceed the longest available pre-
cut jumper cable.
G. Use tie-wraps to neatly coil and secure any excess sensor
cable, jumper cable, branch connectors, etc.

Initial Power-up and Test
Connect the cable to the selected instrument and test the
system.
• ApplypowertotheTraceTekinstrumentandlookfora“Normal”
indication.
– On TTC-1, TTSIM-1A or TTSIM-2 family, there will be a green
LED and no other red or yellow LEDs.
(On TTSIM-1A and TTSIM-2 the green LED will flicker off
every 10 seconds.)
– On TTSIM-1, Normal Condition is indicated by a steady
green LED and a momentary flash of the RED LED every 10
seconds.
– On TTDM-128 the alpha-numeric display will indicate a
channel number and display the words SYSTEM NORMAL.
• IftheYellowLEDisoninanyoftheseinstrumentsorthewords
“Cable Break” or “Loop Break” is displayed, then the cable
system must be inspected for loose connections, missing end
terminations until the cable continuity is established and the
“Normal” condition is achieved.
• LEAKtestingcanbedonewithamappingcap(TT-MAPPING
CAP-PC). The MAPPING CAP simulates a leak at the location
where it is inserted into the system.
– For TTC-1, TTSIM-1 and TTSIM-2 a red LED will indicate that
the simulated LEAK has been detected.
– For TTSIM-2 and TTDM-128 a leak location will be displayed
in feet or meters (as selected) in addition to the red LED
indication
• ForlargerpipingsystemswithTTDM-128orTTSIM-2,the
MAPPING CAP should be moved sequentially to each accessible
connector. Note the distance displayed on the as-built drawings.
This will become the basis for the System Map.
• CreateaSystemMapshowingwheresensingcablesandalarm
modules have been installed. The System Map will include
the beginning and end of sensing cables, and location of any
connections. If using locating alarm modules, the System Map
should include distance readings at significant landmarks
(beginning and end of system, changes of direction, branches,
valves, low points, etc.).

Symptom Possible Cause and Correction
Green LED not visible on TraceTek
instrument
System is not powered. Check power wiring. Check circuit breakers that may have been
tripped. On TTDM-128 check fuse and replace if necessary.
Leak alarm
(TTDM-128 message and red LED)
(SIM Red LED ON)
This is an indication of a LEAK event.
For leak locating modules (TTDM-128 and TTSIM-2): Using leak distance indication and System
Map as a guide, investigate system condition, work to locate and repair leak.
For non-locating modules: Work to locate and repair the leak. (If your system is constructed
with multiple sensor cable segments, using an end termination (TT-MET-PC) to break the sys-
tem into sections can help in locating the leak. Work outward from the alarm module using the
end termination to establish a temporary end of the circuit, then sequentially move outward
adding one cable segment at a time).
Once the leak is repaired, remove excess water from sensing cable and synthetic fiber jacket.
Typically this will clear the Leak Alarm or LEAK condition (Red LED on SIM).
In order to clear the Service Req’d (or Service condition), moisture levels on sensor cable and
synthetic fiber jacket need to be reduced with further drying.
Note: When the Service Req’d or SERVICE condition exists (Yellow LED), leak location ac-
curacy is reduced for a new leak.
Yellow LED visible on TTC-1, TTSIM-1A,
TTSIM-2 or flashing yellow LED on
TTSIM-1
Could be cable break or service indication. Refer to alarm module instructions for more infor-
mation.
For Cable break indication:
Check for loose connectors, missing end terminations, broken jumper wires or physical dam-
age to the cable. Repair or replace cable if necessary. The TT-MET-PC end termination can
be used to isolate a damaged section by working outward from the instrument using the end
termination to establish a temporary end of the circuit then sequentially moving outward add-
ing one cable segment at a time.
“SERVICE Req'd” message
(TTDM-128 Only)
This is an early warning message from the TTDM-128 panel indicating that the cable is becoming
damp, but not yet to the level that constitutes a leak. The TTDM-128 panel may display a location
in square brackets. If a location is displayed, that location should be investigated for possible
sources of condensation/drips. The square brackets indicated that the leak signal is not strong
enough for an accurate location calculation, so the indicated locations may include some error.
Red LED fails to turn off after leak is re-
paired, and leak alarm reset attempted
Cable and over-braid are still damp. Allow more time for cable to dry or investigate leak site to
make sure that water is not pooling under or behind the sensor cable.
Leak location seems inaccurate in
actual leak situation
More that one leak may be present or the cable may be damp in several locations. If the sys-
tem is monitored by a TTDM-128, check the event history to see if there is an earlier indica-
tion of a nearby leak or a SERVICE NEEDED message. If necessary use the end termination
to break the system into smaller segments and work outward to isolate each leak location in
multiple leak scenarios.
Leak locations seem inaccurate or
unstable during mapping tests
Make sure that the simulated leak (MAPPING CAP) is kept in place for at least 30 seconds. The
location circuitry in the instruments require a steady leak location in order to compute an accurate
distance. Removing the simulated leak too quickly induces a random error.
